Impetuous, single-minded and beautiful, Markham was a noted non-conformist, even in a colony known for its colourful eccentrics. She married several times, but accounts of her life indicate that she was not a faithful spouse. Her unconcealed 1929 affair with Prince Henry, the son of England's King George V, led her husband's brother, Sir Charles Markham, to threaten the British royal family with naming the prince in an embarrassing divorce suit. The Windsors promptly cut the romance short; Beryl was bought off with a capital trust of £15,000 from Prince Henry's own funds, from which she drew a modest annuity for the rest of her life.
She befriended the Danish writer Karen Blixen during the years that Blixen was managing her family's coffee farm in the Ngong hills outside Nairobi (in the film rendering of those years, Out of Africa, Markham is represented by an outspoken, horse-riding tomboy named Felicity). When Blixen's romantic connection with the hunter and pilot Denys Finch Hatton was winding down, Markham started an affair with Finch Hatton herself. Largely inspired by Finch Hatton, she took up flying, which she continued to pursue after Finch Hatton's death in an airplane crash. She worked for some time as a bush pilot, spotting game animals from the air and signaling their locations to safaris on the ground. She also mingled with the notorious Happy Valley set, but was never a full-fledged "member" of the decadent crowd.
When Markham decided to take on the Atlantic crossing, no pilot had yet flown non-stop from Europe to New York, and no woman had made the westward flight solo, though several had died trying. Markham hoped to claim both records. On September 4, 1936, she took off from Abingdon, England. After a 20-hour flight, her Vega Gull, The Messenger, suffered fuel starvation due to icing of the fuel tank vents, and she crash-landed near Cape Breton, Nova Scotia (her flight was, in all likelihood, almost identical in length to Mollison's). In spite of falling short of her goal, Markham had become the first woman to cross the Atlantic east-to-west solo, and the first person to make it from England to North America non-stop. She was celebrated as an aviation pioneer.
Markham chronicled her many adventures in her memoir, West With The Night, published in 1942. Despite strong reviews in the press, the book sold modestly, and then quickly went out of print. After living for many years in the United States, Markham moved back to Kenya in 1952, becoming for a time the most successful horse trainer in the country.
"Did you read Beryl Markham's book, West With The Night? ...She has written so well, and marvellously well, that I was completely ashamed of myself as a writer. I felt that I was simply a carpenter with words, picking up whatever was furnished on the job and nailing them together and sometimes making an okay pig pen. But this girl, who is to my knowledge very unpleasant and we might even say a high-grade bitch, can write rings around all of us who consider ourselves as writers ... it really is a bloody wonderful book."
Why Hemingway expressed such a strong personal distaste for Markham is not clear, since there is no evidence that he knew her well. He did, however, know many of her friends, and Markham always generated torrents of gossip.
Intrigued, Gutekunst read West With The Night and became so enamored of Markham's prose that he helped persuade a California publisher to re-issue the book in 1983.. The re-release of the book launched a remarkable final chapter in the life of the eighty-year-old Markham, who was lauded for her three final years as a great author as well as flyer.
She died in Nairobi in 1986.
According to the 1993 biography, "The Lives of Beryl Markham," by Errol Trzebinski, the book's real author was her third husband, the ghost writer and journalist Raoul Schumacher. Trzebinski also claimed that Beryl Markham had an advance from Houghton Mifflin to do a book on the famous international jockey Tod Sloan, that Raoul Schumacher was supposed to write. Apparently Schumacher never did, and she was forced to go it alone, resulting in a manuscript submission that the publisher rejected as worthless, and not from the same person who had written West With The Night.
But in her biography of Markham, Straight On Till Morning, author Mary S. Lovell, who visited Markham in Nairobi and interviewed her extensively shortly before Markham's death, disputes the claim that Schumacher made substantive contributions to West With The Night. From her research, Lovell concluded that Markham was the sole author, although Schumacher did edit the manuscript; instead, Lovell credits Antoine de Saint Exupery, another of Markham's lovers, with being the inspiration behind Markham's clear, elegant language and storytelling style.
